1. 1A. 1B. The amounts of time per workout a student uses an elliptical at the UCF gym are normally distributed with a mean of 18.9 minutes and a standard deviation of 2.15 minutes. If a random student at the UCF gym was selected, then what is the probability that this student used the elliptical for more than 20.2 minutes? 1A. If a random student at the UCF gym was selected, then what is the probability that this student used the elliptical between 17 and 21 minutes?
